腎盂および尿管の通過障害に対する腎盂・尿管形成術の治療成績

A FOLLOW-UP STUDY OF PYELOPLASTY AND URETERAL ANASTOMOSIS FOR HYDRONEPHROSIS DUE TO OBSTRUCTION AT THE URETEROPELVIC JUNCTION OR AT THE MIDDLE URETER

　腎盂・尿管形成術は，今日までに諸家により種種の手術術式が工夫され良好な成績が報告されているが，いまだ適応症例の選択ならびに手術方法に関する多くの問題があり，論議されている。

　当教室において1969年より1974年までの6年間に，腎盂尿管移行部（以下UPJと略す）または中部尿管の通過障害のため腎盂形成術ならびに尿管形成術を受け，術後1年以上の観察のできた症例は各々12例と4例である。

From 1969 to 1974 16 patients were treated by pyeloplasty or end to end ureteral anastomosis for hydronephrosis due to obstruction at the ureteropelvic junction or at the middle ureter from the Dep-artment of Urology, Yokohama City University Hospital. These patients have been followed up between 1 to 4 years postoperatively. They were evaluated by Urinalysis, intravenous pyelography and isotope renography. Pyeloplasty was performed in 12 cases with good result in 67% by pyelography and impro-vement in 41% by renography.
